Multi-Chassis Link Aggregation (MCLAG)
•
UNP authentication and classification is supported over MCLAG aggregates, but only for UNP VLAN
configurations at this time. UNP service configurations are not supported in an MCLAG group. The
UNP configuration must be the same on both multi-chassis peers in the MCLAG domain. Any incon-
sistencies in the UNP configuration between the two peers may impact traffic flow, especially if a
failover occurs.
•
The UNP
show
commands contain a multi-chassis configuration status field to indicate if the UNP
component is in synch or out-of-sync between the two peer switches or only applies to the local switch.
See
“Verifying the MCLAG Configuration Status for UNP” on page 27-44
for more information.
•
There is no automatic correction of any UNP configuration inconsistency; it is up to the administrator
to ensure the necessary changes are made to bring the configuration back into synch between the two
MCLAG chassis.
•
During UNP authentication and classification of a MAC address, an SNMP trap is sent if UNP detects
an MCLAG chassis inconsistency.
•
Configuring a MCLAG VIP interface for a dynamic UNP VLAN is not allowed.
For more information about UNP interaction with MCLAG, see
Chapter 10, “Configuring Multi-chassis
Multiple VLAN Registration Protocol (MVRP)
•
MVRP is not supported on UNP ports, however, both features can co-exist on the same switch. The
recommended configuration is to have UNP dynamically create VLAN-port-associations on edge ports
while MVRP propagates the dynamic VLANs down and up stream.
•
UNP supports a dynamic VLAN profile configuration option. When this option is enabled, tagged
packets received on UNP ports that are enabled to trust the VLAN tag, are classified based on the
VLAN tag of the packet. If the VLAN tag matches a MVRP VLAN on the switch and the MVRP
VLAN is not already assigned to a profile:
>
A new profile is automatically created and associated with the MVRP VLAN.
>
The MVRP VLAN is converted to a UNP dynamic VLAN if the UNP dynamic VLAN configura-
tion option is also enabled for the switch.
